NEEDLE HOLDER FOR TALKING MACHINES.

Application filed May 10,

To allwkom it ma/ycmwern:

Be it known thatrI, HERMANN FREDERICK SdHELLING, .a citizen of the United States. residing at Grantwood, in the county of "Bergen and Stateof New Jersey, have in appertains to make and use the same.

My invention relates to sound reproducing apparatus and more particularly to improvements in the'stylus orneedle holding.

device which is necessary on all forms of so-called talking machines. a

One object of my invention Is to provide a needle holding arrangement which is simple to manufacture, of low cost and compact and neat in appearance.

A further object is to provide such a needle holding arrangement so constructed as to-normally hold the needle firmly in place and'yet ermit of its ejection when desired principa ly by the force of gravity and of the insertlon of a new needle with a minimum amount of effort.

These objects and such others as will be apparent as the description proceeds, are attained by the combination and arrangement of parts described in the specification and partlcularly' pointed out in the claims, one practical embodiment of my invention being-shown in the accompanying drawing in which Fig. 1 is a view of the stylus lever and needle holdingdevice, partly in section showing the manner in which it is operated.

Fig.2 represents an end view of the needle ho din device. Fig. 3 represents a section on the e AA of Fig. 1.

Similar'numerals refr to similar parts throughout the several views.

It is a matter of common knowledge that the needles of talking machines must be frequently changed depending upon the quality and nature of the needle itself and the frequency and duration of use of the machine. It is desirable, therefore, that such needle changin may be rapidly and conveniently done an with a minimum of effort on the part of the operator. At the same time,

it is absolutely. essential to the proper and best operation of the machine that the needle when in place may begripped firmly so as not to rock, tilt or slide while in use.

Referring nowtothe drawing in which I opening 7.

have illustrated one mode of applying my invention for the purposes recited, the diaphragm has attached to it by wax 3 or other desired. means, the stylus arm 1 pivoted as at 2 m the usual way. At the needle end of the arm is a compartment in which the slldlng pm 13 is located having an operating head 8 and passing through the ide opening 15. A flattened portion 14 0 the "pin enables the set screw 9 to limit the inward motion of the pin by abutting the face 17 and to limit the outward motion by abutt ng the edge 18. The pin 13 is essentlally cylindrical, with the flattened portion spoken of and a portion cut away forming V-shapedgrip 16 which co-operates with-a flat side of the triangular opening 7 through which the needle 6 passes. A'spring 12 is held within the casing 10 by the pin or screw 11 the head of which serves a be described presently. I The spring 12 acts against the pin 13 holdmg the same towards its outward'posi- .tion and firmly gripping the needle 6 as in a vise, the V-shaped jaw of the pin holding.

the needle 6 against the flatface 19 of the To remove the needle it is not necessary to turn the sound box upwardly as heretofore; the head of the pin 11 and'the head 8 o-f.the button 13 are grasped between the thumb and forefinger and pressure is ap plied, compressing the spring 12 and positively releasing the needle. 6 so that it may fall out free'of the flat face 19 by the action of its own weight.

should stick in the V-notch of the button v.13, the end 20 of the opening 7 will knock off If in any conceivable manner the needle purpose to and free the needle as the button is pressed farther in to the right as shown. A new needle may be inserted easil by pressing the button-13 fully in and w en the needle is insertedin the opening '7 the button is released, automatically straightening the needle inthree directions by the faces of the clamping jaws and holding the needle firmly bythe action of the spring.

Having thus described my. invention and one method of utilizing the same, what I desire to claim is 1 1. In a needle holding device, a compartment containing a spring, a pin co -operatin with said spring and having a button, and a flattened portion, a set screw abutting said flattened portion and limiting the motion thereof, a, flot jaw on one side of sari i comand having a flattened portion, a, set screw to partment, a Vv-shapeoi jaw on ssid. pin and abutting said flattened portion and. limiting finger grippin means cooperating with the the motion thereof, o fiat jaw on one side button on sei pin, whereby said jaws may of said compartment, 3, 'V-shapeoi jaw on toe separated. said. in and finger gripping means compris- 2. In a needle holding device, a, comliart ing a button co-operating 1 with said first no merit containing a spring, means for hohinamed finger gripping means, whereby said ingsaid spring and having finger gripping jaws may be separated. I means, o pin (lo-operating with. said spring nrrnmm rmznnmcng swarms.
